ROIERT H. MILLER, F DiETROIT, MICHIGAN, ASSIGNOB T0 DETROIT STOVE IFOEXS, OF

DETROIT, A MICHIGAN, A

CORPORATION 'or MICHIG STOVE CONSTRUCTION.

To all lwlw/m, t may concern.'

Be it known' that I, ROBERT H. MILLmaa citizen of the United States of America, county of Wayne -and State of Michigan, have invented certain new and useful Improvements in Stove Constructions, of which the following is a specification, reference being had Itherein to the accompanying drawings.

This invention relates tions such as electric ranges or the like.

The invention generally resides in the various features of construction and arrange# ment of parts.

AmongA the objects of the invention are to4 provide a construction in which the insulated 'walls are built up of blocksor the like which can be readlly assembled; to

v provide an improved arrangement for the electrical connections to the ovens; to prevent any grease or other substance from injuring-the switch terminal s; and in general to provide a new and improved stove construction or electric range.

In the drawings: Figure 1 is a rear rview of an electrlc I range embodying my'invention;

Fig. Zgis a vhorizontal section -on the line 3 is a .vertical sectionv on the line 3-3of Fig.1; l

Fig. 4 1s 'an enlarged vertlcal sectlon throug vone of the top platesof the stove;

- Fig. 5 is a vertical sectional view through ,the oven;`

Fig. 6 isha view similar to at right angles thereto. l

In detail A designatesl an electric ran e which, as shown 'inthe drawings, is oft e high oven type having adjacent the open burner section B a pair of ovens, such as the main oven C and the broiler oven ID. Suitable resistance or heating units E and E are mountedin the ovens-'C and D and also lsuitable heating vunits F for the top plates F.'

Heretofore in the construction of ovens Fig. 5 taken or electric stoves it has been usual to fill in'the space Ibetween the walls G -and G with an insulating material packed into the space between these walls.

The present invention contemplates an 'improved arrangement whereby the insulatin space between the Ivarious walls and is built up with lnsulator blocks H.

or otherwise'formed into' the The various blocks have lap-V will avoid the formation of air spaces, this arrangement further facilitating the assembhng of the insulating lining in the stove. c

At the rear ofthe ovens the resistance elements E and Ek are provided vwith terminal `blocks Kand K. In the novel conin the drawings these blocks are located in a chamber formed by a vent pipe or conduit L. As shown in Fig. 1 this conduit at its lower end has an offsetportion L through which the leading inwires M are conducted to thel terminal blocks K and K', the lower end of the vent pipe L being also used as part of thechamber for the'leadin in wires. The connection between the roiler chamber D and the 'vent pipe or chamber L is through one or more baille plates or chambers N and N so that the gases passing through the open- .mgs O are compelled to baille in the chambers N and N before passingout through the openings O in the rear wall. It will noticed Vthat 4the openings O are so l0- cated that 'the gases passing to the vent are compelled to pass over the terminal blocks K and K, cessive heating of. the latter.

he connection to the ventv pipe from the a port or ports Q and out pipe connection Q.

The inventlon also resides in the improved arrangement vwhereby injury to the switch blocks R'is revented. As showndn` Fig. 4 the switch b ocks are located at the front of the stove and in order to prevent any grease or other material passing down from the hot plate andinjurlng the terminal connections, mounted in a recess member S having at its terminating in a trough or conduit T by means of which any substance leakin throughl from the hot plate is conducted down to the drip pan T. At the lower end the housin S is formed with a supplemental housin in which the usual fuse block plugl is located. This plug is accessible through a door V'. p

From the above description it will be apparent that the construction is one which can be economically manufactured and in Patented June 3, 1919.

2. In an electric range, the combination of superposed ovens, of resistances therefor,

6. In an electric range, the combination `with an oven, of a heating vresistor there-I within, electrical connections for` said resistor, terminal blocks for said electrical connections, and an air vent secured to the oven andy forming a housing for said electrical connections and terminal blocks, the from the oven into the air vent being 'located adjacent the terminal block to compel a passage of air adjacent the terminal block to cool the same.
